Description
Technical Field
[0001] This utility model relates to the field of guardrail technology, and in particular to a road guardrail with good buffering performance. Background Technology
[0002] Traffic guardrails are traffic safety facilities installed on the outer side of road shoulders, traffic dividers, and sidewalk curbs. They absorb collision energy by deforming themselves or by allowing vehicles to climb, thereby changing the direction of vehicle travel, preventing vehicles from going off the road or entering the oncoming lane, and minimizing injury to occupants.
[0003] In practical use, if the guardrail has poor buffering performance, it will be difficult to mitigate the impact force and improve the vibration reduction performance when a vehicle hits it, thus failing to improve the safety of drivers. Therefore, it is necessary to propose a road guardrail with good buffering performance to solve the above problems. Utility Model Content

Therefore, this utility model proposes a road guardrail with good buffering performance.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A road guardrail with good cushioning performance includes a guardrail body. The inner wall of the guardrail body has multiple first grooves, each containing a slidable guardrail rod. Each guardrail rod has a sponge fixedly fitted inside it. A first shock absorber is fixedly connected to one side of each guardrail rod. The end of the first shock absorber facing away from the guardrail body is fixedly installed inside the guardrail body. A protective plate is fixedly connected to one side of each guardrail rod. A second shock absorber is rotatably connected to one side of the protective plate. A mounting frame is fitted onto the surface of the guardrail body. An opening is provided within the mounting frame, and a connecting plate slides vertically within the opening. A cavity is provided within the mounting frame. A second groove is provided inside the guardrail body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figure 1-5 An embodiment of this utility model provides a road guardrail with good buffering performance, including a guardrail body 11. Multiple first grooves 9 are formed on the inner wall of the guardrail body 11. Guardrail rods 10 are slidably fitted into each of the multiple first grooves 9. A sponge 17 is fixedly fitted into each guardrail rod 10. A first shock absorber 14 is fixedly connected to one side of the guardrail rod 10. The end of the first shock absorber 14 facing away from the guardrail body 11 is fixedly installed inside the guardrail body 11. A protective plate 12 is fixedly connected to one side of the guardrail rod 10. A second shock absorber 13 is rotatably connected to one side of the protective plate 12. A mounting frame 1 is fitted onto the surface of the guardrail body 11. An opening 5 is formed in the mounting frame 1. A connecting plate 7 slides vertically through the opening 5. A cavity 2 is formed in the mounting frame 1. A second groove 6 is formed inside the guardrail body 11.
[0024] The first groove 9 serves as a storage space, enabling the connection between the first shock absorber 14 and the protective rod 10, and the connection between the rubber pad and the protective rod 10, when the protective rod 10 is fitted inside the guardrail body 11, thus achieving an effective road guardrail with good buffering performance. When the connecting plate 7 passes through the opening 5 and the second groove 6, the connection between the guardrail body 11 and the mounting frame 1 is achieved, completing the assembly and use of this device.
[0025] Preferably, the mounting frame 1 has a through hole 4, which is connected to the cavity 2.
[0026] By setting the through port 5, the connecting plate 7 can be inserted into the mounting frame 1.
[0027] Preferably, a rubber strip 15 is fixedly connected to one end of the guardrail 10, and the end of the rubber strip 15 facing away from the guardrail 10 is fixedly connected inside the guardrail body 11.
[0028] The cushioning and protection of the guard rod 10 are enhanced by the rubber strip 15.
[0029] Preferably, a groove 16 is provided inside the guardrail body 11, and the end of the second shock absorber 13 facing away from the guardrail 10 is slidably connected in the groove 16, and the surface of the guard plate 12 is fitted in the first groove 9.
[0030] Preferably, the upper end face of the connecting plate 7 is fixedly connected to the limiting plate 8, and the lower end face of the limiting plate 8 overlaps the upper end face of the mounting frame 1.
[0031] The connecting plate 7 can be easily removed upwards from the mounting frame 1 and the guardrail body 11 by means of the limiting plate 8.
[0032] Preferably, the mounting frame 1 has a third groove 3, and the surface of the connecting plate 7 is simultaneously slidably fitted into the first groove 9 and the third groove 3.
[0033] Working principle: First, fluid is injected downwards into cavity 2 through through hole 4, increasing the weight at the bottom of mounting frame 1 and improving its stability. When the worker inserts the guardrail body 11 into mounting frame 1, the connecting plate 7 slides downwards towards the through opening 5 and the second groove 6 via the limiting block, until the bottom of the connecting plate 7 abuts into the third groove 3, completing the stable connection between mounting frame 1 and guardrail body 11. Because a sponge 17 is fixedly fitted inside the guardrail 10, and the sponge 17 has good elasticity, it deforms to absorb the impact force when subjected to impact. This deformation... The process prolongs the impact time, thereby reducing the damage to the object caused by the instantaneous impact. At the same time, under the action of the first damper 14, the first damper 14 and the second damper 13 are usually composed of springs and dampers. The spring is responsible for absorbing vibration and storing energy, while the damper is used to suppress the spring's bounce and consume the kinetic energy stored in the spring, thereby reducing or eliminating vibration. When the protective rod 10 is impacted, it will deform in the first groove 9, which can drive the second damper 13 to slide in the slide groove 16, giving the protective rod 10 a buffer time and preventing the protective rod 10 from quickly resetting and affecting its vibration damping ability.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
